This is a bot which searches the Twitter public timeline for mentions of IPv6. Any URLs mentioned in those tweets whose hosts do not have an AAAA record (i.e. do not have IPv6 support) are clearly meant to be ironic, for why would anyone be commenting on IPv6 if they've not tried to deploy it yet? Your irony is @IPv6fail's invitation to jokingly lament the lack of support for a decade-old networking protocol by the content provider in question.
After the shoot, Laura said that she was "paying for it now, but worth every second of it" — mission accomplished, and I'm really pleased with the results.
